[0002]

2. Description of the Related Art For example, as shown in FIG. 11, there is a type in which a wall material S is horizontally installed on the outer surface of a building. This horizontal wall material S
For example, as shown in FIG. 12, the horizontally long metal surface member 1 has male and female connecting portions 2.3 formed on the upper and lower ends thereof. The male connecting portion 2 includes an upper side wall 4 in which an upper end of the surface material 1 is bent inward at a substantially right angle, and an inner end of the upper side wall 4 is temporarily raised upward and then folded back downward to form a fitting projection. It comprises a portion 5 and a fixing portion 6 formed by raising the lower end of the fitting convex portion 5 again upward. The female connecting portion 3 has a lower side wall 9 in which the lower end of the surface material 1 is bent inward at a substantially right angle, and an inner end of the lower side wall 9 is once raised upward and then folded back downward to form an inverted U-shaped cross section. And a fitting concave portion 11 which is formed in a shape and is fitted into the fitting convex portion 5.

When the wall material S is horizontally stretched, the fixing portion 6 at the upper end of the wall material S is fixed to the wall base material with a drilling screw or the like, and the fitting convex portion 5 of the wall material S is horizontally stretched to the upper side. The fitting recessed portion 11 at the lower end of the lower wall material S is fitted, and the lower side wall 9 of the upper wall material S and the upper side wall 4 of the lower wall material S are made to face each other so that the joint 15 in the lateral direction between both walls 4 and 9 is formed. To form. And
As shown in FIG. 13, joint members 16 are arranged at the left and right lateral ends of the upper and lower wall members S, respectively. The joint member 16 includes a joint cover 19 and a cover mounting member 20. The cover mounting member 20 is fixed to the wall base material 13 in the vertical direction, and the caulking material is provided between the cover mounting member 20 and the end portion of the wall material S. Fill 33. The projection 32 of the rear joint cover 19 is press-fitted into the groove 28 of the cover mounting member 20 to cover the joint in the vertical direction between the ends of the wall materials S and S that are laterally adjacent to each other.

[0004]

However, in the above-described structure for accommodating the end portions of the wall material S for horizontal stretch, as shown in FIG. 12, rainwater is contained in the lower wall 9 of the upper wall material S and the lower wall of the wall material S. Blow from the direction of arrow A into the joint 15 between the upper wall 4 of the material,
Subsequently, there was a problem that it flowed on the upper side wall 4 along the fitting convex portion 5 in the direction of the arrow B and flowed into the joint member 16 to corrode the wall base material 13 at that location, or penetrate into the room. .

Originally, the caulking material 33 filled between the joint member 16 and the end portion of the wall material S is a portion which plays a role of preventing such rainwater infiltration. However, in the actual horizontal installation, there are cases where the end portion of the wall material S is dimensionally cut at the site. In such a case, the wall material S cannot be cut accurately, or the wall material S cannot be cut.
May be laid horizontally while tilting sideways. Therefore, it is difficult to secure a gap of a predetermined size between the joint member 16 and the end of the wall material S, and the caulking material 33 should be sufficiently filled. I couldn't do many things. For this reason, the problem of rainwater infiltration as described above occurred.

In the worst case, the end portion of the wall material S may come into contact with the cover mounting member 20 and a gap for caulking filling may not be formed therebetween.
As a result, not only is it impossible to fill the caulking material 33, but the cover mounting member 2 is used when the joint cover 19 is mounted.
The groove 28 of 0 cannot be expanded and deformed.
In addition, there is a problem in caulking and joint member mounting that it is difficult or impossible to press-fit the protrusion 32 of the joint cover 19 into place.

Between the upper side wall 4 and the lower side wall 9 on the back surface side of the surface material 1, a heat insulating and sound insulating material 12 such as a gypsum board excellent in incombustibility or a rock wool board excellent in incombustibility and water resistance may be lined. This is preferable in terms of obtaining heat insulation and sound insulation effects, but this heat insulation and sound insulation material 12 is not always necessary.

The wall member S having the above-mentioned structure is shown in FIG.
As shown in FIG. 6, the fixing portion 6 is fixed to the wall base material 13 such as the main pillar, the stud, or the furring strip with the fastener 14 such as a self-drilling screw or a tapping screw. Next, another same wall material S is placed on this wall material S. At this time, the fitting convex portion 5 at the upper end of the lower wall material S is fitted to the fitting concave portion 11 at the lower end of the upper wall material S. And the lower side wall 9 of the upper wall material S is butted against the upper side wall 4 of the lower wall material S to form a joint 15 between both walls 4 and 9. As the joint 15, instead of forming a butt joint as shown in FIG. 2, the lower side wall 9 of the upper stage wall material S and the upper side wall 4 of the lower stage wall material S are separated from each other as shown in FIG. The joint 15 may be formed.

FIG. 1 and FIG. 3 are detailed views of the end portions of the wall material S, which are horizontally stretched in the vertical direction in this manner, in the lateral direction. The joint member 1 is preliminarily attached to the wall base material 13 such as main pillars, studs, or furring strips existing at the ends of the wall material S.

Then, the end portion of the wall material S is laterally stretched so as to face the wall surface 23 of the cover mounting member 20, but at this time, the end portion of the wall material S is set to the first position.
The wall material S is made close to or in contact with the wall surface 24.
A gap W sufficient to fill the caulking material can be reliably formed between the end portion of the second wall surface 26 and the second wall surface 26.
Specifically, the gap W has a width of at least 5 mm and a depth of about 10 mm. This gap W is obtained by dimensionally cutting the end portion of the wall material S on site and bringing the cut surface of the end portion of the wall material S close to or in contact with the first wall surface 24 even if it is slightly inaccurate. Can be held securely.

Thus, the caulking material 33 is connected to the gap W to fill the wall surface 25 to a depth. Then, the end portion of the fitting convex portion 5 and the facing portion of the second wall surface 26 can be completely waterproof-sealed with the caulking material 33, so that even if rainwater is present on the upper and lower wall materials S as shown by arrow A in FIG. Joint 15
Even when it is blown onto the upper side wall 4 and flows in the lateral direction B along the fitting convex portion 5 toward the joint member 16, the wall base material 13 at the end of the wall material S is wetted or enters the room. It can be surely prevented. In addition, caulking material 3
3 does not necessarily fill the entire length of the gap W in the vertical direction, and at least the abutting portions of the upper and lower wall members S and the fitting concave and convex portions 11 at the end portions of the upper and lower wall members S.
It is also possible to prevent the infiltration of rainwater described above by filling the space between the fitting portion 5 and the second wall surface 26.

After the caulking material 33 is filled, the joint cover 19 is attached by press-fitting the protrusion 32 into the groove 28 of the cover attaching member 20. In this case, a gap W is formed between the second wall surface 26 of the cover mounting member 20 and the end of the wall material S, and the caulking material 33 that is compressively deformable exists in this gap W, so that the second wall surface 26 is When the projection 32 is press-fitted, the caulking material 33 can be expanded and deformed through compression, and the projection 32 can be press-fitted into the groove 28 without difficulty.

In the above embodiment, the joint member 16 is formed by combining the joint cover 19 and the cover mounting member 20.
The wall surface 23 having the above-mentioned predetermined cross-section has first and second wall surfaces 24 and 26 and a connecting wall surface 25 as shown in FIG.
It may be formed in an integral shape having. Further, the joint member 16 is made by pressing a metal plate,
